Be it knownthnt l, HARRY L. WILSQN, n. citizen of the Unitecl States, ieniding et Erie, in the county of Erie and State of Penneylvenia, have invented certain new end useful Improvements in Dry Pipes for Boilersyenil 'I do hereby declare the following to bee full, clear, and exact description of tlie invention, such es will ennfole others skilled in 'the 'art le which it appertnine to maize enfl use tire seme.

This invention reietes to rlry pipes for boilers, the object in 7eiew ioeingto provide en atte'chment for boilers oonneeteti with the eteamoutlet and .nmenged onfgftile `ineiole of toe boiler no eo to revent'tlefi'tin; oi" the wete? omi 4permi-tting the eeein to ne @oliv- .erel .to sin e eteam-.ontietgimee Sonie. eteie ne, possible; Y

By ineens oi.' the invention the etearn is tzaen from n large eren et 'the highest poneible point within the boiler. f

The detailed objects nnfl advantages of the invention will more fully ippenrin the course of the snbjoined deeeription.

The invention consists in e dry pipe for steam-boilers embodying certain novel features anfl details or construction end arrangements of parte, an hereinafter fully described, illustrated in the dreivinge, and incorporated in the claims. 1

in the accompanying drawings, Figure l. is n lon gitndinal section of the boiler, taken also through a combination dry pipe'nnfl neperw tor constructed in eocorflanee with 'this invention. Fig. 2 is e transverse vertical seetion through the same. Y

Siinilarnnmerele of reference designate cor responding parte in the drawings.

Referring to the drawings, l designates en ordinnrysteoimboiler provided with the Bienal steam-outlet wlzicii for convenience ie shown ,located centrally of the top of theooiier.

lo carrying out the present invention I employ a pipe 3, which is made in sectional form, comprising :in upper, inner, and emellei` seotion 4 and in outer, lower, and larger seotion 5. The upper section 4, which forms n. separator, or, in other words, a. ilevice for separating the steam end water of condenseion, is in the forni of e, channel-bor, comprising an. upper horizontal well or body portion 6, leavinrr 'oepening parallel longitudinal f ile-,ngen 7 and cloeel et oo'tlfl emile 'Soy ineens of panel-ent enel iiengee i3. At e control point toe separator or opper section t ie provifierl with en outworly-etening eoimrgemecl:

The dey pipe ne Whole ie supported by menne of boite i8, arranged et suitable intervals end passing lii'ougll the top of the boiler and oleo through the body portions of the upper and lower sections of the dry pipe. The needs these bolts are arranged outside of the boiler, while nuts le are placed upon tne lower enfle o' the boite, and oy menne the dry pipe may be adjusted vertically for vnying the distance between the top t3 of the iienges l1 and the inner Surface of tne baile. Finally the lower section 5 is provided nel jeeentto each en'r with drip-holes l5, Wlii. l1'

will allow the wetter of condemnation eonieiner in. the @my pipe to fell back into the heile?.

The object of the errengenient above de noribed ie to peni/ide e tortnone passage for the steam, the letter having to pees iii'st oval Athe upper edges of the lengen vll and then through horizontal row@ of perforations 16, located. slightly aioove the bottom :eges of tie fenges 7 and' 8 of the upper section or separator 4, the steam time nding ite Way to the outlet 2. The speen between the images ll end tine boiler is limited to about twice the area. of the steam-pipe, eompeiling the steam' to iiow ont over the full etree of said cli pipe. A further obieot of the inner chienne ber is to forrnatortuoue passage forthe steam, thus eliminating any retninetl wetter in the steam, and this Water fails to the bottom of the outer channel and then gasses through tltodripL holes beek into the boiler. ln tiliemenner oi *heee nnte tile sections of' i op the water isrrirevented from being lifted by the steenremdr allowed to enter directly into the outlet, and the steam is consequently de-v [oV 1. The combination with the outlet of a steam-boiler, of a separator in the form of a channel-bar communicating with the steamoutlet and having depending longitudinal end flanges .perforated near their lower edges, a

x 5 second channel-bar of larger size disposed rei versely to the aforesaid channel-bar with its fian ges extending outside of the flanges of the first-named channel-bar, and means for supporting and'adj usting both ohannel-bars,snb

e semfiany as described.

2. The Combination with the steam-outlet of a boiler, of a dry pipe in the 'form of a channel-bar having an upwardly-extending surrounding ange, bolts for adjust-ably supporting'said pipe', and a separator consisting of 25 a second channel-bar disposed reverselyto the irst-named channel-bar and having a depending surrounding flange which rests on' the lower channel-bar and is provided with openin gs near its bottom edge, tho first-named 3o.

channel-bar being provided at suitable points with drip-openings, and the upper channel- -bar having communication with the steamoutlet, substantially 'as described.

In testimony whereof I aix my signature 3 5 in presence of two witnesses.
